STAVE-l/[AGHINIE.`

Specification of Letters Patent No;A 11,600, dated August 29, 1854.

To all whom t may concern Be it known that I, I. B. DUDREY, of Athens, in the county of Athens and State of Ohio, have invented an Improvement in Machines for Dressing Staves, and that the following is a full, clear, and exact description of the principle or character which distinguishes it from all other things before known and of the usual mannerof making, modifying, andv using the same, reference being had to the accompanying drawings,` of

which* y Figure 1 is an elevation of the machine on the feeding side. Fig. 2 is an elevation of the opposite side where the staves are delivered. Fig. 3 is a detached view ofthe cutter head and knives. Fig. 4 is a hori- Zontal section through the knives when in] the act of cutting the stave.

My invention consists in a certain arrangement of the knives, cutter head and guides in a stave dressing machine for cut ting and dressing staves at one operation as hereafter set forth.

A vibrating arm a one end of which is pivo-ted to the frame of the machine carries 71, is cut into this part of the jaw so as t0 form a hollow space between the inside of thejaw and the knife through which space the shavings are to pass. The upper edge e f, as well as the lower edges e', f, of the knives are sharpened. On one side of the cutter head thereare two feed rollers z' i through which the stave is carried to the knives, which in their circular vibrating motion dress it simultaneously on both sides and both ways-that is during their upward as well as downward motion. On the other side of the cutter hea'd the stave enters between a pair of guide rollers one of them Z being concave and the other k convex so as to suit the shape of the stave. By these means the stave is kept steady during the whole of the operation.

What I claim as my improvement in dressing staves is- The employment of two knives substantially of the form and action set forth,

within the curved jaws of a vibrating cutter head, for cutting the staves both ways" that is, in the back and forth motion of the cutter'head,-all in the manner set forth; and in combination therewith I claim the curved guides or guards for holding the stave when the same has passed the feed rollers, in the manner and for the purpose.n set forth.
